Description

Technical Field

[0001] This utility model relates to the field of tobacco harvesting technology, specifically to a mechanically assisted tobacco harvesting device. Background Technology

[0002] Currently, tobacco harvesting is predominantly done manually. Statistics show that losses during the harvesting process account for approximately 3-5% of the total yield, directly caused by misharvesting, missed harvesting, and mechanical damage. Based on a yield of 200 kg of tobacco per mu (approximately 0.16 acres) and a current purchase price of 38 yuan / kg, the harvesting process results in a loss of 228 yuan per mu for tobacco farmers, which is considerable.

[0003] During manual tobacco harvesting, pickers play three roles: picking, bundling, and transporting. The specific work scenario is as follows: On a hot summer morning, pickers, carrying headlamps, enter the field to pick tobacco leaves, bending over to pick 10-20 leaves at a time, cradling them as they pick, and then placing the fresh leaves on the ridges, piling them into small heaps. Next, bundling workers, carrying fresh tobacco bags, gather the small heaps of leaves, stacking them into large heaps of 50kg each, and then wrap them into bundles. Finally, transporters carry the bundles of tobacco leaves on their shoulders to the roadside for temporary storage, until the transport vehicle arrives at the field, at which point they are loaded onto the vehicle again.

[0004] There are three main reasons for misharvesting and missed harvesting of tobacco leaves when harvested entirely by hand: First, tobacco harvesting occurs during the hottest season, and the harvesters' labor capacity decreases under high temperatures; second, to avoid the high temperatures, harvesters carry headlamps into the fields before dawn, and the light from headlamps alone is insufficient, leading to misjudgments; third, there is a serious loss of young and middle-aged labor in rural areas, and the concentrated demand for labor during the harvest season results in the use of a large number of older harvesters with poor labor capacity.

[0005] Harvesting tobacco leaves by hand requires multiple handling, placement, and transfers, resulting in mechanical damage to the leaves.

[0006] In the existing technology, there are two methods that use auxiliary transport vehicles to assist manual harvesting of tobacco leaves, which can reduce bumps and injuries to a certain extent, but also have significant drawbacks.

[0007] A patent titled "Tobacco Field Harvesting Vehicle" (patent number CN201020604020.7) discloses a field-assisted tobacco harvesting and transportation machine. The machine consists of a frame, wheels, a working platform, and tobacco clamps. It moves across rows, completing leaf harvesting, clamping, and field transportation in a single operation. The aim is to reduce the amount of manual labor required for transporting tobacco leaves between rows, minimize the number of leaf transfers, and reduce leaf damage. However, the machine requires manual loading of tobacco leaves and clamping of the tobacco. Because the working platform is higher than the tobacco plants, the harvesting vehicle is too high off the ground, making it inconvenient for manual labor and reducing its practicality. Furthermore, the machine lacks power and requires manual pushing, limiting its capacity for loading large quantities of tobacco leaves.

[0008] A patent titled "Tobacco Field Harvesting and Transport Device" (CN201821840319.5) discloses a tobacco leaf field transport device, including a frame, wheels, and a working platform. It features fixed points for tobacco leaf baling bags and can complete tobacco leaf stacking and transport operations in one go, reducing the workload of manual back-and-forth transport and secondary bundling. However, this machine is unpowered, relies on manual pushing, and cannot handle large-capacity tobacco leaf loading. Therefore, we propose a mechanically assisted tobacco leaf harvesting device. Utility Model Content

[0009] The purpose of this invention is to provide a mechanically assisted tobacco harvesting device, which aims to reduce tobacco harvesting losses, lower the labor load of harvesters, and improve manual efficiency.

[0010] To achieve the above objectives, a tobacco leaf mechanical auxiliary harvesting device includes an inter-row transporter that travels in conjunction with the furrows, wherein the furrows are provided with ridge slopes at both ends.

[0011] The inter-row transporter includes a chassis and guide wheels. The bottom of the chassis is symmetrically equipped with guide wheels, and the two guide wheels travel on the surface of the ridge slope. The top of the inter-row transporter is symmetrically equipped with railings at both ends, and fresh leaf bags are placed between the two railings.

[0012] Preferably, one end of each of the two railings is symmetrically provided with a front handle, and the other end of each of the two railings is symmetrically provided with a rear handle.

[0013] Preferably, the leaf bag is made of a flexible material and has a square structure.

[0014] Preferably, the fresh leaf bag has through holes spaced at equal intervals along its edge.

[0015] Preferably, the chassis is self-powered, and its walking speed is adjustable.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model employs a self-propelled, powered inter-row transporter to assist in tobacco harvesting. Harvesters are responsible for picking the tobacco leaves, while the inter-row transporter is responsible for transferring them. The transporter is self-powered and can move independently. The machine travels within the furrows and is equipped with balancing and guiding devices to autonomously correct its direction of travel. Guardrails are installed on both sides of the machine. The transporter's base is flat.

[0018] 2. When the guide wheel of this utility model comes into contact with the slope of the ridge, the slope of the ridge generates a reaction force on the guide wheel, thereby correcting the walking direction of the inter-ridge conveyor, so that the inter-ridge conveyor can travel autonomously in the furrow, reducing the amount of work that harvesters need to do to control the direction of the machine.

[0019] 3. By using an inter-row conveyor in conjunction with manual harvesting, tobacco leaves can be quickly transported to fresh leaf bags, reducing the time and physical exertion of manual handling and thus greatly improving harvesting efficiency.

[0020] 4. In this utility model, the tobacco leaves are directly placed in fresh leaf bags after being manually picked, which avoids damage or random stacking of tobacco leaves during transportation, helps to maintain the neatness of the tobacco leaves, avoids the phenomenon of loose bags during subsequent packaging, and ensures the quality of tobacco leaves.

[0021] 5. In the harvesting process, tobacco leaves can be directly packaged on the inter-row conveyor, eliminating the need for additional transportation. When the fresh leaf bags reach their maximum capacity, they can be unloaded and delivered directly to the field, greatly improving the continuity and efficiency of the overall operation process.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 and Figure 2This utility model provides a technical solution: a tobacco leaf mechanical auxiliary harvesting device, including an inter-row transport machine 1, which travels in the furrow 41, and the two ends of the furrow 41 are provided with ridge slopes 42.

[0031] It should be noted that during the operation, the picking workers can easily control the movement of the inter-row conveyor 1. The inter-row conveyor 1 moves along the furrow 41 without damaging the tobacco leaves.

[0032] Please see Figure 2 The inter-row conveyor 1 includes a walking chassis 11 and guide wheels 12. The bottom of the walking chassis 11 is symmetrically equipped with guide wheels 12, and the two guide wheels 12 travel on the surface of the ridge slope 42. The top two ends of the inter-row conveyor 1 are symmetrically equipped with railings 14, and fresh leaf bags 2 are set between the two railings 14.

[0033] It should be noted that the fresh leaf bag 2 is fixed to the inside of the railing 14 on the inter-row conveyor 1 by means of a rope or hook. The two guide wheels 12 travel on the surface of the ridge slope 42. When the guide wheels 12 come into contact with the ridge slope 42, the ridge slope 42 generates a reaction force on the guide wheels 12, thereby correcting the traveling direction of the inter-row conveyor 1, so that the inter-row conveyor 1 can travel autonomously in the furrow 41, reducing the amount of work that the harvester needs to do to control the direction of the machine.

[0034] Please see Figure 2 Two railings 14 are symmetrically and integrally provided with front handles 13 at one end, and symmetrically provided with rear handles 15 at the other end.

[0035] It should be noted that by setting up the front handle 13 and the rear handle 15, during the operation, the picking workers can easily operate the front handle 13 and the rear handle 15 to control the movement and ridge changing of the inter-row conveyor 1. Through the one-person or two-person operation mode, the operation is more flexible and adaptable to different operation scenarios and needs.

[0036] Please see Figure 3 The fresh leaf bag 2 is made of a flexible material and has an overall square structure.

[0037] It should be noted that the flexible fresh leaf bag 2 allows the tobacco leaves to be easily and directly packed on the inter-row conveyor 1 during the harvesting process, eliminating the need for additional transportation. When the fresh leaf bag 2 reaches its maximum capacity, it can be unloaded and delivered directly to the field, greatly improving the continuity and efficiency of the overall operation process.

[0038] Please see Figure 3 The edge of the fresh leaf bag 2 has through holes 21 at equal intervals.

[0039] It should be noted that the through hole 21 makes it easy to tie the fresh leaf bag 2 to the railing 14, and also makes it easy to pack the harvested tobacco leaves.

[0040] Please see Figure 1 The chassis 11 is self-powered, and its walking speed is adjustable.

[0041] It should be noted that the introduction of the inter-row conveyor 1 can effectively reduce the workload of picking workers in carrying tobacco leaves and reduce physical exertion. In particular, the adjustable walking speed design can be flexibly adjusted according to the actual picking speed, further optimizing the work rhythm.

[0042] Please see Figures 1-6 When using this utility model of a mechanically assisted tobacco harvesting device, the following steps should be followed:

[0043] S1. Preparations before operation:

[0044] S11. Harvesters should be trained and proficient in using inter-row operations;

[0045] S12. Refill the oil or electricity of the inter-row conveyor 1, check that all operating handles and buttons are functioning normally, check that the steering wheels and guide wheels 12 at the bottom of the walking chassis 11 move freely, and check that all bolts of the inter-row conveyor 1 are tight.

[0046] S2, Machine enters the ground:

[0047] S21. Drive the inter-row transporter 1 into the furrow 41 of the tobacco field with the front wheels facing the direction of travel. When there is a drainage ditch at the edge of the field, add a ramp for the vehicle to enter the field, and two people assist in entering the field.

[0048] S22. Place the fresh leaf bag 2 on the inter-row cart and fix it to the hook on the railing 14 so that the picked tobacco leaves can be placed directly.

[0049] S23. Start the inter-row conveyor 1 and set the machine forward speed to match the manual tobacco leaf picking speed;

[0050] S3, Harvesting:

[0051] S31. Manually pick tobacco leaves and place them directly onto the inter-row conveyor 1. The inter-row conveyor 1 moves within the furrow 41 on its own.

[0052] S32. If the conveyor encounters potholes or large weeds, it may tip over or slip, requiring manual adjustment of the machine in a timely manner.

[0053] S33. The tobacco leaves should be neatly placed on the fresh leaf bag 2 to avoid the bag from falling apart during subsequent wrapping;

[0054] S4. Packing and unloading: When the tobacco leaves are piled up to the maximum capacity, the picking of tobacco leaves should be stopped, and the fresh leaf bags 2 should be packed directly on the conveyor. The machine should then be driven to the field to unload the goods.

[0055] S5. Machine-assisted ridge replacement:

[0056] S51. When operated by one person, the harvester stands in front of the inter-row conveyor 1, holds the front handle 13 to lift the front wheel, and moves the machine forward at the same time. The harvester moves backward while changing rows. Alternatively, the harvester stands behind the machine, holds the rear handle 15 to lift the front wheel, and moves forward while changing rows. When operated by two people, both people hold the front handle 13 and the rear handle 15 at the same time and lift the front wheel to change rows.

[0057] S52. After the ridge replacement is completed, continue with step S3 to harvest the tobacco leaves.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
